Validering af Kapitalfremskrivnings Script.

Hey eksperter.

Bryggede lige dette sammen, på en lille time.

kan i se nogle fejl / mangler osv ?

koden :

<?php

$debt          = 28785.75; // What you owe in total.
$interest      = 1.1255; // Interests each year. 12.55%
$year          = date("Y", time())+1; // Next upcomming month.
$month        = date("n", time())+1; // Next upcomming month.
$payment      = 2000; // Payment each month.

$month_names  = array(1 => 'January','February','March','April','May','June','July','August','September','October','November','December');

############  Dont touch anything below here. #############

echo "Year ".($year-1)."<br>\n";
echo "Value: ".$debt."<br>\n";
echo "Monthly Payment : ".$payment."<br>\n<br>\n";

for ($i = 1; $debt >= $payment; $i++) {
if($month % 12 == 1) {
  $month = 1;
  $new_debt = ($debt*$interest)-$debt;
  $new_debt = number_format($new_debt, 2, '.', '');
  echo "<br>\nYear ".$year."<br>\n";
  echo "Old Value : ".$debt."<br>\n";
  echo "Interests added: $new_debt<br>\n";
  echo "New Value : ".number_format($debt*$interest,2,'.', '')."<br>\n<br>\n";
  $debt = number_format(($debt*$interest) - $payment,2,'.', '');
  echo "<b>".$month_names[$month].":</b> &nbsp; ".$debt."<br>\n";
  $year++;
$month++;
}
else { 
  $debt = $debt - $payment; 
  echo "<b>".$month_names[$month].":</b> &nbsp; ".$debt."<br>\n";
  $month++; 
}
}

echo "<br>\n<u>Running time: ".$i." months.</u><br>\n";
